The vertex descriptor from which to copy information.
A new vertex descriptor that is an indpendent copy of the specified vertex descriptor.
A vertex descriptor does not own vertex data—vertex data belongs to the
vertex property of the mesh that owns a vertex descriptor—so this method does not copy vertex data. A call to the
copy method uses this initializer to produce a fully independent copy of the original instance.
